RSB Machine Servo Conversion – Precision Automation for Roving Frames

Our RSB Machine Servo Conversion System is designed to modernize conventional RSB (Roving Section/Back Roller) machines by replacing mechanical or relay-based drives with servo motor-based automation. This upgrade ensures precise drafting, uniform roving, improved production efficiency, and enhanced operator safety, making it ideal for modern spinning mills.

Servo conversion enables accurate control of drafting rollers, bobbin speed, and lift motion, resulting in consistent roving quality, reduced yarn breakage, and minimized downtime.

Key Features of RSB Machine Servo Conversion

• Servo motor-based precise control of all drives

• PLC integration for centralized automation

• User-friendly HMI touchscreen interface

• Accurate bobbin build and drafting control

• Integrated safety interlocks and alarms

• Real-time machine monitoring and diagnostics

• Energy-efficient operation with reduced mechanical wear

• Simplified wiring and maintenance
